GTA Pest Control Pricing 2026

Pest control in the GTA is priced per treatment, per pest type, or as a package deal for recurring prevention. Severity of infestation is the biggest cost driver — a minor ant problem costs $150; a severe bed bug infestation can cost $2,000+. Most exterminators require an inspection ($80–$150) before quoting, which is often credited toward treatment. (Serving Markham, Ontario.)

Most Common GTA Pest Problems

Heat treatment kills bed bugs at all life stages (eggs, nymphs, adults) in a single treatment by raising room temperature to 55°C for several hours. Chemical treatment is cheaper but requires 2–3 treatments over 3–4 weeks and does not kill eggs (which hatch after treatment). For severe infestations, heat treatment's higher upfront cost is almost always more economical than multiple chemical retreatments. (Serving Markham, Ontario.)
